Answer:
x = 3.5
y = 11.75
Step-by-step explanation:
-9x - 2y = -55
6x - 4y = -26
Step 1:
-2(-9x - 2y = -55) → 18x + 4y = 110
Step 2:
18x + 4y = 110
<u> 6x - 4y = -26</u>
<u> 24x </u>= <u>84</u>
24 24
x = 3.5
Step 3:
6(3.5) - 4y = -26
21 - 4y = -26
<u> -21 -21 </u>
<u> -4y </u>=<u> -47</u>
-4 -4
y = 11.75
7x + 6y < 42
6y < -7x + 42
y < -7/6x + 7
slope = -7/6....y int = (0,7)...x int = (6,0)...it will be a dashed line...shading will be below the line....so start at (0,7)...and since the slope is -7/6...go down 7 spaces and to the right 6 spaces, and keep doing this and u will cross the x axis at (6,0)
7x + 6y > - 42
6y > -7x - 42
y > -7/6x - 7
slope = -7/6...y int = (0,-7)....x int = (-6,0)....line will be dashed....shading will be above the line...so start at (0,-7) and since the slope is -7/6...go down 7 spaces and to the right 6 spaces...keep doing this and u will cross the x axis at (-6,0)
