☃Question asked:
7−4x=21−1x
☃Simplify both sides of the equation:
7−4x=21−1x
☃Let's simplify step-by-step:
7−4x=21−1x
7+−4x=21+−x
−4x+7=−x+21
☃Add x to both sides:
−4x+7+x=−x+21+x
−3x+7=21
☃Subtract 7 from both sides:
−3x+7−7=21−7
−3x=14
☃Divide both sides by -3:
−3x/−3 = 14/−3
☃Answer:
x=−14/3

☃Hope this helps!☃
