X = y+2<br> x+4y=7 <br><br> Please help!
spayn [35]
Since x = y + 2

so
y + 2 + 4y = 7

5y + 2 = 7

5y = 7-2

5y = 5

y = 1

x= y + 2

x = (1) + 2

x = 3

(x,y) = (3,1)

4x=3y+23<br> 4y+3x=-19<br> solve by substitution. No files pls
LuckyWell [14K]

Answer:

x = ⁷/₅

y = ⁻²⁹/₅

Step-by-step explanation:

4x = 3y + 23 (×3)

12x = 9y + 69

4y + 3x = -19

3x = -4y - 19 (×4)

12x = -16y - 76

∴ 9y + 69 = -16y - 76

25y = -145

y = ⁻²⁹/₅

12x = 9(⁻²⁹/₅) + 69

12x = 69 - ²⁶¹/₅

12x = ⁸⁴/₅

x = ⁷/₅
