How do I solve for y if x is 7

Step-by-step explanation:

x does equal 7 so you know your vertical angle rule. 9x + 42 is same side exterior with 4y - 13, so the sum of them is 180.

9(7) + 42 + 4y - 13 = 180 and

63 + 42 + 4y - 13 = 180 and

92 + 4y = 180 and

4y = 88 so

y = 22

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
