Answer:
x = 2
Step-by-step explanation:
Given
2.5(6x - 4) = 10 + 4(1.5 + 0.5x) ← distribute parenthesis on both sides
15x - 10 = 10 + 6 + 2x , that is
15x - 10 = 16 + 2x ( subtract 2x from both sides )
13x - 10 = 16 ( add 10 to both sides )
13x = 26 ( divide both sides by 13 )
x = 2
Root both sides of the equation
x+3= plus or minus root 7
Subtract 3 from both sides.
Answer:
x=16 because the proportional size, this also means that if the -84 becomes 16 in proportion size.
