Answer:
x = 4
Step-by-step explanation:
Start by setting the two expressions equal to each other, since they're the same height.
6 + 15x = 6x + 42
Subtract 6x from both sides
6 + 9x = 42
Subtract 6 from both sides
9x = 36
Divide both sides by 9
x = 4
Without a calculator, you can cross multiply
$4.5 since 1.26/7 is .14 and need 25 so it’s 4.5
Square root of 300
