-6+7s-4r-2 use s=7 and r=-7

Simplified

I hope I helped you^_^

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

x/3-10=8

x/3=18

x=48
