Answer:
x = 24
Step-by-step explanation:
1.) put the equations together and equal them to 180
2x + 4 + 6x - 16 = 180
2.) combine like terms
8x - 12 = 180
3.) divide both sides by 8
8x = 192
4.) simplify
x = 24

Also who is Francine?
Answer:
The answer is = −70s+63
Step-by-step explanation:
7(1−10s+8)
=(7)(1+−10s+8)
=(7)(1)+(7)(−10s)+(7)(8)
=7−70s+56
=−70s+63
Answer:
Solution given;
<M=5x+10
<R=55
<M+<R=90°
<u>5</u><u>x</u><u>+</u><u>1</u><u>0</u><u>+</u><u>5</u><u>5</u><u>=</u><u>9</u><u>0</u><u>°</u><u>[</u><u>is</u><u> </u><u>a</u><u> </u><u>required</u><u> </u><u>equation</u><u>]</u>
<u>now</u><u> </u><u>solving</u><u> </u><u>it</u>
<u>5</u><u>x</u><u>=</u><u>9</u><u>0</u><u>-</u><u>6</u><u>5</u>
<u>5</u><u>x</u><u>=</u><u>2</u><u>5</u>
<u>x</u><u>=</u><u>2</u><u>5</u><u>/</u><u>5</u>
<u>x</u><u>=</u><u>5</u><u>i</u><u>s</u><u> </u><u>your</u><u> </u><u>answer</u><u>.</u>
You can reword the equation 6x+y=9 to
Y=6x+9
Then plug-in y=6x+9 into the equation 2x+3y=-5
Plug this 2x+3(6x+9)=-5
2x+18x+27=-5
Then solve it from there
