<em>1</em><em>8</em><em>0</em><em>-</em><em>1</em><em>4</em><em>2</em><em> </em><em>=</em><em>3</em><em>8</em><em> </em>
<em>3</em><em>8</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>correct</em><em> </em><em>answe</em><em>r</em>
Step 1; multiple equation 2 by -2: 14x+8y=-18
step2: subtract this new equation from equation 1 to eliminate x:
2y-8y=18-(-18)
-6y=36
y=-6
step 3: substitute y=6 in equation 2: -7x-4*(-6)=9, -7x=-15, x=15/7

Answer:
X = - 12.
Step-by-step explanation:
17 = 5 - x
17 = 5 + - x
17 = - x + 5
Then, flip the equation.
-x + 5 = 17
Then subtract 5 from both of the sides.
-x + 5 - 5 = 17 - 5
-x = 12
Then divide
-x/ -1 = 12/1
x = - 12.
Hope this helps!
4/12 because you do 1×4=4 and 3×4 =12 ...but whatever you do to one side you do to the other side
