Answer:
a) x = 4
b) x = 1
Explanation:
a)
multiply both sides by 2 so we can simplify the fraction by getting rid of 2
4x - 1 = 2x + 7 transfer like terms to the same side of the equation
4x - 2x = 7 + 1
2x = 8 divide both sides by 2
x = 4
b)
again, get rid of the fraction by multiplying both sides by 3
9x + 6 = 2x + 13 transfer like terms to the same side of the equation
9x - 2x = 13 - 6
7x = 7 divide both sides by 7
x = 1
