Answer:

He could use y+3x=-4

Step-by-step explanation:

When we subtract 3x on both sides, we get y=-4-3x, which means we just solved a variable and can substitute into the other equation 2x-3y=-21

lutik1710 [3]

Answer:

WX = 8 mm

Step-by-step explanation:

To be able to solve for WX, we need to first find the size of angle \angle z.

We use the law of sines in the blue triangle to do such:

\frac{sin(z)}{11} =\frac{sin(133)}{20} \\sin(z)=\frac{11\,sin(133)}{20} \\sin(z)=0.4022

Now we can use this value in the larger right angle triangle where WX is the opposite side to angle  \angle z, and the 20 mm side is the hypotenuse:

sin(z)=\frac{opposite}{hypotenuse} \\sin(z)=\frac{WX}{20}\\0.4022=\frac{WX}{20}\\WX=20\,(0.4022)\\WX=8.044\,\,mm

which rounded to the nearest integer gives

WX = 8 mm
