What don't you understand about these problems?
I really just don't understand algebraic equations like these
or how to do them
It won't help you if we just give you the answers. You must go back and study your text. When you have one problem you don't understand, post it and someone will probably help you.
I know how to do these now thanks

Ps. No matter what day you see this you can ask me any questions about that lesson if you don't just want the answers and I will help you through it until you understand!
1) To find the value of -5g-6 when g = -2, substitute -2 in place of g in the expression.
Therefore, -5(-2)-6 = 10-6 = 4.
So, when g = -2, -5g-6 equals 4.
2) The algebraic expression for the sum of 3 coins and c coins can be written as 3 + c.
3) To find the value of x that satisfies the equation x-2 = 16, isolate x by performing the inverse operation.
Add 2 to both sides of the equation: x-2+2 = 16+2.
This simplifies to x = 18.
So, the value of x that satisfies the equation is 18.
4) To solve the equation z/-12 = -5 mentally, multiply both sides of the equation by -12.
This yields z = (-5)(-12), which simplifies to z = 60.
Thus, the value of z that satisfies the equation is 60.
5) To estimate the solution of the equation x-8.1 = 5.3 to the nearest whole number, add 8.1 to both sides of the equation.
This gives x = 5.3 + 8.1 = 13.4.
Rounding 13.4 to the nearest whole number, we get x ≈ 13.
6) To solve the equation 14 = t-44, isolate t by adding 44 to both sides of the equation.
This results in 14 + 44 = t, which simplifies to t = 58.
Hence, the value of t that satisfies the equation is 58.
7) To solve the equation -30 = j+50, isolate j by subtracting 50 from both sides of the equation.
This gives -30 - 50 = j, which simplifies to j = -80.
So, the value of j that satisfies the equation is -80.
8) To solve the equation 2.8x = -9.24, divide both sides of the equation by 2.8.
This yields x = -9.24 / 2.8, which simplifies to x ≈ -3.3.
Therefore, the value of x that satisfies the equation is approximately -3.3.
9) To solve the equation 5.8 = z/2.2, multiply both sides of the equation by 2.2.
This gives 2.2 * 5.8 = z, which simplifies to z ≈ 12.76.
Hence, the value of z that satisfies the equation is approximately 12.76.
