Answer:
- x = 37 1/2
- x = 2
Step-by-step explanation:
Parallel lines divide transversals proportionally. I like to write the proportions so the variable is in the numerator. Then the solution is obtained by multiplying by the denominator of the variable term.
1. x/20 = (46 -16)/16
x = 20(30/16)
x = 37.5
__
2. (x +4)/13.5 = 4/9
x +4 = 13.5(4/9) = 6
x = 6 -4
x = 2

Answer:
x=9
Step-by-step explanation:
To solve, simplify the equation them isolate x.
8(2x- 6) = 96 Distribute over brackets by multiplying
16x - 48 = 96 Add 48 to both sides
16x = 144 Divide both sides by 16
x = 9 Final answer
