Solve the inequality 1.4z + 2.2 > 2.6z − 0.2

z < 2

Step-by-step explanation:

1.4z + 2.2 > 2.6z - 0.2

add 0.2 to both sides

1.4z + 2.4 > 2.6z

subtract 1.4z from both sides

2.4 > 1.2z

divide by 1.2

2 > z

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
