Answer: x = -19
Step-by-step explanation:
-4(x + 1) - 3 = - 3(x - 4). original equation
-4x -4 -3 = -3x + 12 distributed terms into the parentheses
-4x -7 = -3x + 12 added together terms (simplified terms)
-4x = -3x + 19 added term to the other side of the equation
-1x = 19 added term to the other side of the equation again
x = -19 divided by negative one
Answer:
Below.
Step-by-step explanation:
This is the correct solution:
6 - 2x + 5 + 4x
= -2x + 4x + 6 + 5
= 2x + 11.
It looks like they added unlike terms together (4x + 5) to give 9x (incorrect) then added the 4x to give 13x.
m∠CBD = m∠BFE Given
m∠CBD + m∠DBF = 180° Supplementary Angles
m∠BFE + m∠DBF = 180° Supplementary Angles
