If you would like to solve the system of equations, you can do this using the following steps:
x = y - 3
x + 3y = 13 ... y - 3 + 3y = 13
___________
<span>y - 3 + 3y = 13
</span>4y = 13 + 3
4y = 16
y = 4
<span>x = y - 3 = 4 - 3 = 1
(x, y) = (1, 4)
</span>
The correct result would be A) (1, 4).
Answer:
-72 is the answer to this problem, hope it helps.
Step-by-step explanation:
5 * 3x + 4x = 15x + 4x = 19x
S<span>tep-1 : Multiply the coefficient of the first term by the constant </span><span> <span> 3</span> • 4 = 12</span>
<span>Step-2 : Find two factors of </span> 12 <span> whose sum equals the coefficient of the middle term, which is </span><span> 13 </span><span>.
</span><span><span>
-12 + -1 = -13</span><span>
-6 + -2 = -8</span><span>
-4 + -3 = -7</span><span>
-3 + -4 = -7</span><span>
-2 + -6 = -8</span><span>
-1 + -12 = -13</span><span>
1 + 12 = 13 </span></span>
