I broke it all the way day half of 51 is 25 in a half and half of 25 is 12 in half so if Jimmy lifted twice as much he may have lifted 25 in a half and bob left 12

0.4x - 2.5 = 1.3x + 4.7
qwelly [4]
Simplifying
0.4x + -2.5 = 1.3x + 4.7

Reorder the terms:
-2.5 + 0.4x = 1.3x + 4.7

Reorder the terms:
-2.5 + 0.4x = 4.7 + 1.3x

Solving
-2.5 + 0.4x = 4.7 + 1.3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1.3x' to each side of the equation.
-2.5 + 0.4x + -1.3x = 4.7 + 1.3x + -1.3x

Combine like terms: 0.4x + -1.3x = -0.9x
-2.5 + -0.9x = 4.7 + 1.3x + -1.3x

Combine like terms: 1.3x + -1.3x = 0.0
-2.5 + -0.9x = 4.7 + 0.0
-2.5 + -0.9x = 4.7

Add '2.5' to each side of the equation.
-2.5 + 2.5 + -0.9x = 4.7 + 2.5

Combine like terms: -2.5 + 2.5 = 0.0
0.0 + -0.9x = 4.7 + 2.5
-0.9x = 4.7 + 2.5

Combine like terms: 4.7 + 2.5 = 7.2
-0.9x = 7.2

Divide each side by '-0.9'.
x = -8

Simplifying
x = -8
