5.3x-7=2.3x%2B5 Start with the given equation


10%285.3x-7%29=10%282.3x%2B5%29 Multiply both sides by 10 to move the decimal on each number 1 time. This will make every number a whole number.

53x-70=23x%2B50 Distribute and multiply


53x=23x%2B50%2B70Add 70 to both sides


53x-23x=50%2B70 Subtract 23x from both sides


30x=50%2B70 Combine like terms on the left side


30x=120 Combine like terms on the right side


x=%28120%29%2F%2830%29 Divide both sides by 30 to isolate x



x=4 Divide
