For the first question, triangle ABC is congruent to triangle DEF by the ASA (angle side angle)
For the second question, triangle MNO is congruent to triangle PRQ by the SAS (side angle side)
For the third question, triangle UVW is congruent to triangle XYZ by the SAS (side angle side)
Step 1:
Line up respective variables in column.
.................(1)
.................................(2)
Step 2:
We need to multiply first equation with -2 so that the coefficient of b becomes equal and opposite of -8.
*2
...................(3)
Step 3:
Add equation (2) and (3)

The b terms will cancel out and we are left with only a terms.
-11a = 22
dividing both sides by -11
a=-2
Step 4:
plug this value of a in equation (1) to find value of b,



b=-9
Answer : a=-2 and b =-9
X=4
-4x4=-16+14=-2
2x4=8+7=15
-2 x 15=30
