gladu [14]3 years ago

Answer:

X = -2

y = 2

Step-by-step explanation:

Substitute y=x + 4 in the second equation to find x

x+4 = 2x + 6

subtract x from both sides

4 = x + 6

subtract 6 from both sides

-2 = x

put -2 in for x in the first equation

y= 2

<h3>What are expressions?</h3>

Expressions are mathematical statements that are represented by variables, coefficients and operators

<h3>How to translate the algebraic expression?</h3>

The expression is given as

21 increased by twice Gail's height

Where

g represents Gail's height

So, we have

21 increased by twice Gail's height ⇒ 21 increased by twice g

Twice means 2*

So, we have

21 increased by twice Gail's height ⇒ 21 increased by 2g

increased by means +

So, we have

21 increased by twice Gail's height ⇒ 21 + 2g

Hence, the expression represented by 21 increased by twice Gail's height is 21 + 2g
