I need help with figuring out the equation 5(2x+3)-8x=7
5(2x+3)-8x=7
10x+15-8x=7
2x+15=7
2x=7-15
2x=-8
/2 /2
x= -4
uh -8/2=-16 yes?
No, actually -8 divided by 2 is equal to -4. Let me explain how to solve the equation step by step:
1. Start with the given equation: 5(2x+3)-8x=7.
2. Begin by distributing the 5 to both terms inside the parentheses: 10x + 15 - 8x = 7.
3. Combine like terms by subtracting 8x from 10x: 2x + 15 = 7.
4. Next, isolate the variable term by subtracting 15 from both sides: 2x = 7 - 15.
5. Simplify the right side of the equation: 2x = -8.
6. Divide both sides of the equation by 2 to solve for x: x = -8 / 2.
7. Finally, simplify the division: x = -4.
Therefore, the solution to the equation 5(2x+3)-8x=7 is x = -4.
