can u solve the equation
1)1.2x= 2.3x-2.2
2)[x-4]= 15
3)[13+2x]= 5
1) 1.2x = 2.3x - 2.2
2.2 = 2.3x - 1.2x
2.2 = 1.1x
x = 2
2) x - 4 = 15
x = 15 + 4
x = 19
3) 13 + 2x = 5
2x = 5 - 13
2x = -8
x = -8/2
x = -4
it's all about getting the same variables to the same side of the equation. put the x's on one side of the equation(doesn't matter which side) and the numbers on the other side. then you can solve easily.
1.1x+1.2x-5.4= -10
To solve the equations:
1) 1.2x = 2.3x - 2.2
To get the variables (x) on one side, we can subtract 1.2x from both sides:
1.2x - 1.2x = 2.3x - 1.2x - 2.2
This simplifies to:
0 = 1.1x - 2.2
Next, we want to isolate the x term, so we can add 2.2 to both sides:
2.2 = 1.1x - 2.2 + 2.2
Simplifying this gives:
2.2 = 1.1x
To solve for x, divide both sides by 1.1:
2.2 / 1.1 = 1.1x / 1.1
This simplifies to:
2 = x
So the solution to the equation is x = 2.
2) [x - 4] = 15
To solve this equation, we need to isolate the x term. Since the x term is inside brackets, we will first remove the brackets by distributing the value inside them:
x - 4 = 15
Next, we need to isolate x, so we can add 4 to both sides:
x - 4 + 4 = 15 + 4
This simplifies to:
x = 19
So the solution to the equation is x = 19.
3) [13 + 2x] = 5
Similar to the second equation, we need to remove the brackets by distributing the value inside:
13 + 2x = 5
Next, we want to isolate x, so we'll subtract 13 from both sides:
13 + 2x - 13 = 5 - 13
Simplifying this gives:
2x = -8
To solve for x, divide both sides by 2:
2x / 2 = -8 / 2
This simplifies to:
x = -4
So the solution to the equation is x = -4.
Remember, when solving equations, the goal is to isolate the variable by applying inverse operations to both sides of the equation until the variable is by itself.
