Step-by-step explanation:
bcs 3 is the mode you do 3+3
Answer:
a) x = 5
b) x = 4
Step-by-step explanation:
a) 4x - 3 = 2x + 7 collect like terms
4x - 2x = 7 + 3
2x = 10 divide both sides by the coefficient of x
x = 5
b) 2x + 6 = 7x - 14 collect like terms
2x - 7x = -14 - 6
-5x = -20 divide both sidess by the coefficient of x
x = 4
