Solve these simultaneous equations.
4x – 7y = – 5
3x – 2y = – 7
Solution: x=

its line 2 i just added the rest or else it wouldn't let me answer

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629

the answer is  

a.
