Question
Solve the equation
x=−31
Alternative Form
x=−0.3˙
Evaluate
4(x+1)−7x=5
Move the expression to the left side
4(x+1)−7x−5=0
Calculate
More Steps

Evaluate
4(x+1)−7x−5
Expand the expression
More Steps

Calculate
4(x+1)
Apply the distributive property
4x+4×1
Any expression multiplied by 1 remains the same
4x+4
4x+4−7x−5
Subtract the terms
More Steps

Evaluate
4x−7x
Collect like terms by calculating the sum or difference of their coefficients
(4−7)x
Subtract the numbers
−3x
−3x+4−5
Subtract the numbers
−3x−1
−3x−1=0
Move the constant to the right-hand side and change its sign
−3x=0+1
Removing 0 doesn't change the value,so remove it from the expression
−3x=1
Change the signs on both sides of the equation
3x=−1
Divide both sides
33x=3−1
Divide the numbers
x=3−1
Solution
x=−31
