Ms. Pacheco, Mr. Edwards, and Mr. Richards are three math teachers at Turner Middle School. Ms. Pacheco is three years older tha

mina [271]

Ms. Pacheco = P
Mr. Richards = R
Mr. Edwards = E
P = R + 3
E = 2R
R + E = 81
81 = R + 2R
81 = 3R
81 ÷ 3 = R
R = 27
P = R + 3
P = 27 + 3
P = 30
E = 2R
E = 2×27
E = 54

Can anyone tell me what x equals in this scenario. 3/4x=2x-5

Dvinal [7]

Hey There!

The answer to your problem is $x=4$

Subtract 2x from both sides

$3/4x-2x=2x-5-2x$

$-5/4x=-5$

Multiply both sides by 4/(-5)

$(4/-5)*(-5/4)$ x $=(4/-5)*(-5)$
