Find matrix%281%2C3%2C+%22h%28%22%2C4%2C%22%29%22%29 given that matrix%281%2C5%2C+%22h%28%22%2Cx%2C%22%29%22%2C%22=%22%2Cx%2F2-7%29

matrix%281%2C5%2C+%22h%28%22%2Cx%2C%22%29%22%2C%22=%22%2Cx%2F2-7%29

Erase all the x's

matrix%281%2C6%2C+%22h%28%22%2C%22%22%2C%22%22%2C%22%29%22%2C%22=%22%2C%22%22%2F2-7%29+

Put 4's where the x's were:

matrix%281%2C5%2C+%22h%28%22%2C4%2C%22%29%22%2C%22=%22%2C4%2F2-7%29

Simplify the right side:

matrix%281%2C5%2C+%22h%28%22%2C4%2C%22%29%22%2C%22=%22%2C2-7%29

matrix%281%2C5%2C+%22h%28%22%2C4%2C%22%29%22%2C%22=%22%2C-5%29

Easy, wasn't it?
