Maggie's brother is four years younger than twice her age the sum of their ages is 14 how old is maggie?

Step-by-step explanation:

Let x = Maggie's age

2x -4= Maggie brother age

x + (2x-4) = 14

Add 4 to each side

x+2x = 18

Combine like terms

3x=18

Division property of equality

x=6

Input 6 as x in the equation

2(6) -4= 12-4=8

Maggie's brother is 8 years old and Maggie is 6 years old

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

answer: 8d

step-by-step explanation:

45+5= 50+5=55+5=60
