Answer:
Step-by-step explanation:
set it up like this
19x + 11 = 11x + 4
then self like algebra
19x + 11 -4 = 11x + 4 - 4
19x + 7 = 11x
19x -11x + 7= 11x -11x
8x ÷ 8 + 7 ÷ 8
x = 0.875
plug it into
19x + 11
19 × 0.875 + 11 = 27.625
so 27.625 should be your answer
Answer:
Sara's number is 28
Step-by-step explanation:
Let's assign Sara's number the variable x and solve this equation using the information provided.
"If you subtract 14 from my number"
x - 14
"and multiply the difference by - 3"
-3(x - 14)
"the result is – 42."
-3(x - 14) = -42
Now we can solve from here for x.
-3(x - 14) = -42
x - 14 = 14
x = 28
Answer:
if I'm not wrong, its x>34
Step-by-step explanation:
multiply both sides by 3
3(x - 4)/3 > 10 x 3
x - 4 > 30 (simplify)
add 4 to both sides and x > 34
