Solve each system using substitution or elimination. 1) 𝑦=3𝑥−8
𝑦 = 4 − 𝑥
3) 𝑐−5𝑑=2 2𝑐 + 𝑑 = 4
5) 𝑥+𝑦=8 𝑥 − 𝑦 = 4
7) 5𝑠+2𝑡=6 9𝑠 + 2𝑡 = 22
9) 13𝑎+5𝑏=−11 13𝑎 + 11𝑏 = 7
11) 3𝑥−2𝑦=19 5𝑥 + 4𝑦 = 17
2) 4𝑥+3𝑦=11 𝑦 = 3𝑥 − 13
4) 0.5𝑥−2𝑦=17 2𝑥 + 𝑦 = 104
6) 4𝑥−3𝑦=12 4𝑥 + 3𝑦 = 24
8) 3𝑟−5𝑠=−35 2𝑟 − 5𝑠 = −30
10) 2𝑥 + 𝑦 = 5 3𝑥 − 2𝑦 = 4
12) 8𝑥 − 3𝑦 = −11 2𝑥 − 5𝑦 = 27
