164 = 5x - 7(4x - 7) Distribute 7 into (4x - 7)

164 = 5x - (4x(7) - 7(7))

164 = 5x - (28x - 49) Distribute - into (28x - 49)

164 = 5x - 28x + 49 Combine like terms

164 = -23x + 49 Subtract 49 on both sides

164 - 49 = -23x + 49 - 49

115 = -23x Divide -23 on both sides

-5 = x


[you could have just distributed -7 into (4x - 7), then combine like terms, etc. But I didn't know how to write that, sorry]
