Warm Up ResponseSolve

Compute

a)2(x + 4) = 32 x=13 a) -6 + (-7) = -13

b)21 = 2(x + 3) x=7.5 b)-11 – (-23) =12

c)Explain c)Explain

Isolate the variable. Subtracting a neg, is

Use inverse operation like taking away

÷, then inverse of debt (or giving you

addition is subtraction more). 2 negs = +

Mode Mode Mode’s the most, Average is the Mean, Median Median Median always in between
