sophia is 6 years older than her brother eric. the sum of their ages is 28. write and solve an equation to find sophia and Eric'
zimovet [89]

s = 6 + e

s + e = 28

We can use this system of equations to find the exact values of s and e.

We have a current value of s, so we can find the exact value of e now.

e + e + 6 = 28

<em><u>Combine like terms.</u></em>

2e + 6 = 28

<em><u>Subtract both sides by 6.</u></em>

2e = 22

<em><u>Divide both sides by 2.</u></em>

e = 11

Now we have an exact value of e, and can solve for the value of s.

s = 6 + 11

s = 17

Sophia is 17 years old, and Eric is 11 years old.

Solve for x please help
34kurt

Answer:

x = 9

Step-by-step explanation:

By remote exterior angle theorem:

(12x + 14)\degree = (1 + 5x) \degree+ 76 \degree \\ 12x + 14 = 1 + 5x + 76 \\ 12x - 5x = 77 - 14 \\ 7x = 63 \\x =  \frac{63}{7}  \\ \huge \red{ \boxed{ x = 9}}
