Solve the following:<br> 4x-3=2x+7
Harman [31]

Answer:

= 5

Step-by-step explanation:

Add 3 to both sides of the equation 4 − 3 = 2 + 7 4x-3=2x+7 4x−3=2x+7 4 − 3 + 3 = 2 + 7 + 3

Simplify Add the numbers Add the numbers 4 = 2 + 1 0

Subtract 2 2x 2x from both sides of the equation 4 = 2 + 1 0 4x=2x+10 4x=2x+10 4 − 2 = 2 + 1 0 − 2

Simplify Combine like terms Combine like terms 2 = 1 0

Divide both sides of the equation by the same term 2 = 1 0 2x=10 2x=10 2 2 = 1 0

Simplify Cancel terms that are in both the numerator and denominator Divide the numbers = 5

Solution x=5
